The number of ducks in a pond is equal to the square root of the number of fish, and the number of turtles is equal to the cube root of the number of fish. The number of fish in the pond is more than 1 but less than 100. There are no fractional or negative numbers of ducks, fish, or turtles.
Answer:
There are 64 fish, 8 ducks and 4 turtles.
Explanation:
From the question, there can be from 2 to 99 fish in the pond. However, there cannot be fractions in the number of fish, ducks or turtles. Hence, the number of fish must have both of a perfect square and perfect cube. The perfect squares from 2 to 99 are 4, 9, 16, 25, 36, 49, 64 and 81. The perfect cubes from 2 to 99 are 8, 27 and 64. Since only 64 fits both criteria, the number of fish is 64. The number of ducks is the square root of number of fish, which is the square root of 64. The square root of 64 can be either positive 8 or negative 8. However, there cannot be negative numbers, so there are 8 ducks in total. The number of turtles is the cube root of the number of fish, which is the cube root of 64 and it is 4.

Fatty acids from ols present in fish Diet adequate in synthetic form of folate Diot rich in fiber Diot low in sodium and high in potassium Reduced risk of neural tube Reduced risk of hypertension Reduced risk of defects and stroko cardiovascular disease Roduced risk of some types of cancer
Answer:
Reduced risk of neural tube defects- diet adequate in synthetic form of folate Reduced risk of hypertension and stroke- diet low in sodium and high in potassium Reduced risk of cardiovascular disease- fatty acids from oils present in fish Reduced risk of some types of cancer- diet rich in fiberExplanation:
As you may already know, the adequate intake of certain nutrients is very beneficial to our body and to improve and maintain our health. That's because these nutrients act in the construction of essential molecules to keep our body functioning in a healthy and adequate way. Among the numerous nutrients necessary for our health, we can mention that the adequate intake of folate has the ability to reduce the creation of possible defects in the neural tube, while a diet rich in potassium can reduce the risks of hypertension, especially if accompanied by a low sodium diet. Following this same reasoning, a diet rich in fiber can reduce the risk of cancer, in addition to promoting good bowel function. Last but not least, a diet rich in fatty acids from fish can reduce cardiovascular disease.

Carbonic anhydrase is an enzyme found in the cytoplasm of a cell. You genetically modified the gene which produces the mRNA for carbonic anhydrase to now include a signal sequence. What will happen when carbonic anhydrase initially binds to a ribosome
Answer:
Explanation:
Carbonic anhydrase modification is a promising strategy for improving the potency and stability of carbonic anhydrase, which is used to expedite CO2 uptake from flue gases. Carbonic anhydrase can be genetically engineered to increase CO2 conversion, absorption of CO2 from a gaseous state into bioactive compounds, and mineral synthesis.
When carbonic anhydrase attaches to a ribosome, the carbonic anhydrase will now be synthesized at first by the free ribosome, after which the ribosome will become a bound ribosome and the protein will be present in the rough Endoplasmic reticulum when the synthesis is complete.
In this case, when carbonic anhydrase initially binds to a ribosome - Carbonic anhydrase initially will be synthesized by free ribosomes, but then these ribosomes then will become bound ribosomes and the protein will be in the rough ER when synthesis is complete
Carbonic anhydrase is an enzyme that helps the rapid conversion to carbonic acids from carbon dioxide and water with protons and bicarbonate ions.
Classified as a metalloenzymeThe modification in the carbonic anhydrase enhances the potency and stability of the enzyme.It can be modified to increase CO2 conversion, absorption of CO2 from a gaseous state into bioactive compounds, and mineral synthesis.Thus, In the case of carbonic anhydrase bound to a ribosome, at first, the carbonic anhydrase will be synthesized by the free ribosome and later the ribosome will become a bound ribosome and the protein will be present in the rough Endoplasmic reticulum once the synthesis process completes.

6-48 In somatic cells, if a base is mismatched in one new daughter strand during DNA replication, and is not repaired, what fraction of the DNA duplexes will have a permanent change in the DNA sequence after the second round of DNA replication
Answer:
1/4
Explanation:
DNA replication is semi-conservative, which means that during this process one DNA strand will be from the original DNA template, whereas the other DNA strand will be newly synthesized. In the first round of DNA replication, daughter cells receive a DNA molecule containing one original DNA strand and one newly-synthesized DNA strand (in this case, one of these daughter cells will contain a mismatch). If the mismatch is not repaired, then in the second round of replication the DNA molecule containing the mismatch would separate during replication, and the DNA strand containing the erroneous nucleotide will serve as a template for the synthesis of a new DNA molecule, thereby producing a permanent mutation.
An enlarged right ventricle both increases oxygen intake and the risk of pulmonary hypertension. How can natural selection
result in an adaption that produces both positive and negative effects?
A) The positive effects appear after reproductive age in certain environments.
B) The positive effects outweigh the negative effects in certain environments.
C) The negative effects appear later in life in certain environments.
D) The negative effects appear before reproductive age in certain environments.
Answer: B
Explanation: I took the quiz on my own and got a 100%
The positive effects outweigh the negative effects in certain environments. Therefore, option (B) is correct.
What is natural selection?In certain environments, an enlarged right ventricle can be advantageous for increasing oxygen intake, such as at high altitudes where there is less oxygen in the air. However, in the same environment or in other environments, an enlarged right ventricle can increase the risk of pulmonary hypertension, which can lead to heart failure.
Natural selection can result in an adaptation that produces both positive and negative effects if the positive effects outweigh the negative effects in certain environments. This can result in the adaptation being favored by natural selection and becoming more common in the population. Over time, this can lead to the adaptation becoming a fixed trait in the population.

PLEASE HELP ASAP!! How neurotransmitters carry nerve impulses across the synaptic cleft
Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite. The binding allows the nerve impulse to travel through the receiving neuron
Another way of thinking is
Neurons talk to each other across synapses. When an action potential reaches the presynaptic terminal, it causes neurotransmitter to be released from the neuron into the synaptic cleft, a 20–40nm gap between the presynaptic axon terminal and the postsynaptic dendrite (often a spine)
Hope this helps =)
Explanation: Neurotransmitters like to travel across the synapse between the axon and the dendrite of the next neuron. They then attach to the membrane of the dendrite. This connection makes it possible for the nerve impulse to travel through the receiving neuron.
Plants use the proton electrochemical gradient across the vacuole membrane to power the accumulation of salts and sugars in the organelle. This accumulation creates hypertonic conditions in the vacuole. Why does this not result in the plant cell swelling and bursting?
Answer:
Due to movement of water to the outside environment.
Explanation:
This hypertonic solution is not result in the plant cell swelling and bursting because hypertonic causes shrinkage of cell instead of swelling. Swelling of cell occurs when the cell experiences hypotonic solution due to presence of less amount of solutes inside the cell. In hypertonic solution, there is less amount of water in the solution as compared to the cell so the water in the cell moves towards outside of the cell causes shrinkage of the cell.

What do populations living at high elevations have to adapt to?
A) lower ultraviolet light intensity.
B) higher average temperatures.
C) lower oxygen levels.
D) higher heart rates among children.
Answer:
c lower oxygen levels
Explanation:
the higher up the person is the closer to the atmosphere so there is less oxygen
The populations living at high elevations have to adapt to lower oxygen levels because at the sea level they at high altitude, there is less oxygen in the air that we breathe. This results that all of the blood from all areas of the lungs, is proportionally short on hypoxic.
What is hypoxia?
Hypoxia is refer to as the condition of the body in which the tissues are starved of oxygen. In its extreme form, where oxygen is entirely absent, the condition is known as anoxia.
The pressure on the body is about the same as ten meters of sea water pressing down on person body all the time. At sea level, air is compressible, then the weight of all that air at height compresses the air around us, making it denser. As the we go up a mountain, the air becomes less compressed and becomes thinner.

Manatees and seals both share some phenotypic similarities that are adaptations to an aquatic environment. However, seals evolved from a bearlike carnivore and manatees evolved from a hoofed mammal. This example shows that __________.
a. evolution is not always unidirectional.
b. evolution can occur rapidly for one species while the other species stays relatively unchanged.
c. similarity is a good predictor of how long it has been since two species shared a common ancestor.
d. evolution is not always divergent.
They are about as different as a leopard and a cow.
Meaning both are mammals of roughly similar size, and sharing a vaguely similar habitat. That’s the end of similarities.
Seals are carnivorous and manatees are plant eaters, and taxonomically they are in different orders. Seals spend much of the time on land, while manatees are completely aquatic. Seals have thick layer of fat and are adapted to Arctic water, while manatees, despite their roly-poly appearance, have almost no fat and do not handle cold water well at all. Here is the closest a manatee ever gets to an iceberg.
